PSA Check your older 6700 Chains
Well, I guess it could be worse.... Riding along minding my own business cooling down the other day. Maybe 15 mph at most after just coming up and over a steep little climb. In the 3rd ring and snap crackle pop! Look back and say crap!
Only reason I can come to is the chain broke and caused the rest. Was not anywhere near the 26 ring at the time so pretty much ruling out the RD. Think what happened is that it broke and in the process of going through the RD it took pretty much everything else with it.
So, broken RD hanger, broken chain and trashed cable housing. Wheel out of true but no broken spokes..... Who said riding was cheap
And before the peanut gallery chimes in about the dirty chain... it was clean at the start of the ride... This is not Southern California
So the Giant is getting new parts..... I really don't mind replacing stuff I wear out but this is a bummer.

Yeah, breaking chains sucks. I've only ever done it once, on my single speed mountain bike. I don't know what spurred the break, but the snap sent me over the bars and cracked my helmet.
And yeah, riding through Washington in the winter is a pretty dirty process. Just ask my brother's campus bike.

Last chain I broke, sent me over the bars, a fun ride in the ambulance, a week in hospital, collar bone, head injury, 3 ribs and cracked scapula. I'd trade that for a broken RD.

That sucks.... and yes I realize it could have been much worse. Rear wheel locked up but was riding up a slight grade just cooling down so.. flat spot on the tire and no crash. I hate broken body parts!

That's exactly what killed my beloved Scott CR1 Sl. I was standing and sprinting, everything broke up, rear wheel locked up, and I kept it upright, skidding to a stop. Mine was a DA chain.

Was it an old chain (not old as in worn, but had you bought it and stashed it for a while?). There were some earlier issues with seemingly bad batches of 6700 chains. https://cozybeehive.blogspot.com/2010...n-failure.html

Steel is real, baby!
I snapped my first chain ever (in 25+ years of riding) a few weeks ago. It also bent my derailleur beyond what could be repaired.
So, about $100 later, I'm back in business. No injuries, thank goodness. I've had enough of those over the past 9 months!

Check out the new Crud Catcher fenders. They added a section to the rear fender help keep crud off the FD and chain. I got sets for my and my wife's backup bikes for riding in all the sand and salt on the roads.

So I checked out my chain, and what do I find? Thanks again to BeeSeeBee for the link above. I now have a 5600 chain on, and this 6700 chain will go to the trash can.

Yikes!
The only other time I've heard of a chain failing that way was some years ago when a friend found cracks like that on a nearly-new Wippermann stainless chain.
Fortunately, he found them before it failed.
Think I'll stick to SRAM and KMC, especially since they include the master links.
